LB1938FA-AH

Overview

The LB1938FA-AH is a single-channel low-saturation forward/reverse motor driver manufactured by onsemi. It operates within a supply voltage range of 2.2V to 10V and supports an output current of up to 800mA. The device utilizes bipolar technology and features a parallel interface for control. It is housed in an 8-pin MSOP package with dimensions of 3mm x 3mm x 1.03mm. The component is designed for general-purpose applications and functions within a temperature range of -20°C to +75°C.

Feature Summary

Single-channel forward and reverse motor driving capability
Low saturation voltage design for improved efficiency
Compact 8-pin MSOP surface-mount packaging

Applications

General purpose motor control systems
Small brushed DC motor drives
Battery-operated devices requiring low voltage operation

Procurement Notes

Verify the specific suffix AH against official onsemi documentation to confirm pinout and electrical characteristics, as suffixes may indicate variations. Confirm end-of-life status through authorized distributors, as availability data indicates potential discontinuation. Ensure the source document explicitly lists the LB1938FA-AH part number to avoid confusion with similar variants like the LB1935FA or standard LB1938FA.

Selection Notes

Select this component for applications requiring a single H-bridge configuration with low voltage operation down to 2.2V. The 800mA output current suits small motors where space is constrained due to the MSOP package. Verify that the required thermal management aligns with the +75°C maximum operating temperature limit specified in the datasheet.

Part Context

The LB1938FA-AH belongs to onsemi's family of low-voltage motor drivers. It serves as a specialized solution for controlling brushed DC motors in portable and battery-powered electronics. The device integrates protection features typical of modern motor driver ICs, though specific details must be confirmed via the official datasheet.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult onsemi technical support or authorized distributor databases for verified cross-reference information.
